Disassembly
1. Isolatethecontrolvalvefromthelinepressure,releasepressure from both sides of the valve body, and drain the
process media from both sides of the valve. If using a power actuator, shut off all pressure lines (or other power
source) to the power actuator, release pressure from the actuator, and disconnect the pressure lines from the
actuator. Use lock-out procedures to be sure that the above measures stay in effect while you work on the
equipment.
See the WARNING at the beginning of the Maintenance section for more information before removing the valve from
the pipeline.
2. Remove line bolting, remove the control valve from the pipeline, and place the actuator/valve assembly on a flat
surface.
3. Remove the actuator cover. Note and mark the orientation of the actuator with respect to the valve body and the
lever orientation with respect to the valve drive shaft, to assist with reassembly.
4. Loosen the lever locking device cap screw. Loosening the lever turnbuckle adjustment is not necessary during
disassembly. When remounting the actuator, the turnbuckle will be used for actuator adjustments.
5. Removing the actuator from the valve:
a. Remove the actuator mounting screws, bolts, or nuts.
CAUTION
When removing the actuator from the valve, do not use a hammer or similar tool to drive the lever or actuator off the valve
shaft. Driving the lever or actuator off the valve shaft could damage the ball, seal(s), and valve.
If necessary, use a wheel puller to remove the lever or actuator from the valve shaft. Tap the wheel puller screw lightly to
loosen the lever or actuator. Do not hit the screw with excessive force. Using excessive force could damage the ball, seal(s),
and valve.
